This invention relates to hatchets, hammers or similar headed tools andto a method of making the. same, and has for an object to provide aheaded tool wherein the head and handleare each made ofa different gradeand character of steel, the head and the ham dle being each made of agrade and character of steel best adapted for the purpose for which itis intended.

It is a further object of this invention to provide a hatchet or headedtool wherein the head may be forged of a high grade tool steel which iscapable of maintaining a keen cutting edge, while the handle may beseparately forged of a high grade ofstructural steel 1 having greatstrength and toughnessand also in which the head and handle-can beseparately heat treated. according to -the character of steel used, tosecure theirgreat est adaptability for the work to beperformed by each.j It is another object of the invention to provide a hatchet, hammer orsimilar tool in-which thehead and handle are so connected that there isno possibility of the head becoming loose on the handle. l 1 Stillanother object of the invention-is to provide a construction forthistype of device which can be more easily manufactured and at lesscost. l

WVith the foregoing and other objects in View, this invention comprisescertain condie in a position. about to be welded together.

modified head and handle, and

Structions, combinations and arrangements of parts as set forth,disclosed and claimed in-the following specification considered inconnection with the accompanying drawings. In the drawings: 4 Fig, 1 isa side View of a hatchetembodylng one form of this invention.

F ig. 2 is a back plan view of the hatchet of Fig. 1.. I Fig. 3 is across section looking in the'direction of the arrows online 3-3 ofFig. 1. Fig. his a section on line 44 of Fig. 1. Fig. 5 shows a view ofthehead and hen Fig. 6 isan end elevation of the handle.

Fig. 7 shows a View similar to Fig. 5 of a Figs.8, 9 and 10 are.fragmentary top views contact therewith as .in Fig. 5, .and is thenindicating different wa ysby which the ham 7 dlemay be welded to thehead. In the construction shownthe hatchet head- 10 includes the,cutting edge 11 on one end.- and the hammer 12 on .theother end andifdesired there may he a claw 13 provided in one side; This head10 ispreferably made of a high grade tool steel which is capable ofmaintaining a keen cutting edge at 11. In the form shown in Figs. 1 to5, which is the preferred form, there is forged integral with the head10 on the rear edge thereof an ear or lug 14; to which the shank 15 ofthe handle 16 is to be welded. The shank 15 is preferably made ofxa highgrade structural steel having strength, toughness and resiliency and isbetter adapted to stand'the' strains of useas a handle than it wouldmade of the same steel-as the head. .The head end of the shank 1:5 maybe of any de sired shape in cross section, but is preferably and shouldbe substantially; rectangular or oval in cros section, similar. to thelugtor car. 14: and if. butt welded tothe lug is placed in weldedthereto. This can be readily done in an clectricfwelding machine whichieats the abutting ends of the lug 14 and the shank or, handle portion15 and forces them; together in the welding operation. This operationproduces a rib 17 all around the welded-joint whichis later ground offso that. to all ap peara'nces the head 10 is forged in one piece withthe handle shank 15, and the welded joint is just as strong as if theywere forged in one piece. Q v

Altho it is preferred to electrically butt weld the handle to the lug weare by .no means limitedto but welding. Other ways ofwelding may be usedas shown in Figs. 8, 9 and 10. As shown in F ig.8 either the end' of thehandle or the end of the lug may be provided with a substantially shapedrecess 26 and theother member with a tapered also be used for electricwelding. Sin'lilarly as shown in:-Fig. 9 the ends of the lugs and handlemay be slanting as indicated-at 28 surfaces of the flanges 19, andtogive a gen-' so they will overlap and may be welded together in thesame manner. In Fig. the overlapped ends are rabbettedas shown at 29 andwelded inthe same way.

The shank extends throughout the en.- tire length of the handle 16 andis preferably substantially I-shaped in cross sectionwitha central plateor web 18 and flanges 19 extending laterally from the opposite sidesthereof and from bothsides of the web as eral oval shape to the grip,and the handle is given a graceful longitudinal cury' ature as shown inFig. 1, so that it will fit properly in the hand. These cheek pieces aresecurely fastened on the opposite sides of the'shank by suitablerivets21, giving a rigid, substantially unitary structure. At their freeends, the cheek pieces are preferably projected outwardly somewhat asshown at 22 to give a sort of rounded enlargement or flange at the endto further improve the grip and prevent tool flying from the users hand.

In the form shown" in Fig.7. the ear or lug 14 has been omitted from thehead 23,

and the shank 24 is butt welded directly to the rear edge 25 thereof,electric butt welds i ng being preferably used as in the form previously described. In this case, however, it

would be better to preheat the head 23. as

it-isa greater mass than" the shank,"so that the two members ormetals'at the point of welding may be of the same temperature,

thereby insuring a firm and secure joint therebetween.-

It is apparent fro'mjthe above'description that this invention providesa tool of this character which is of a very strong con struction inwhich there is absolutely no danger of the head working loose, that thehead being of a high grade tool steel will maintain a keen cutting edgefor a greater length of service, and that the handle being made of ashank of high grade structural steel, will have greaterstrengthytoughness and resiliency to withstand the strains to which itis put,much greater than if itwere made of the same steel as the head. 7

By this construction as above set forth, the head and the handle caneach be made of a steel most suitable for the particular job it has toperform, the head to have the requisite hardness to maintain its keencutting edge,

and the handle tohave therequired strength and resihency andtoi'iglineiss, instead of having to compromise and lose some of thesedeed forv the head, and vice 'versa, the head will maintain its keen'cutting edge much longer than it wouldif it were'made of'the grade orcharacter of'steel'best adapted for use in the handle. Resiliency is avery desirable feature in the handle as it makes the tool much easier onthe hand and arm of the user. ith a properly resilient handle less shockfrom the blow is transmitted 't'othehand and arm and so the toolis lesstiring.

.The forging operations are also much easier and much better forgingscan be produced by for ing the head in one operation and the handle orshank inanother than where they are forged in one piece. This is amaterial advantage even when the head and handle are made'of the samegrade and character of steeh Further, there is much less breakage and,therefore, less waste in manufactureso that a better article can beproduced at less cost. A still further important advantage is that withour improved construction the head and handle can be differ-j ently heattreated to secure their maximum adaptability for the work intended.These heat treatments are controlled according to the steels used andthe effect or character desired in the different parts. In short,the

head, and handle. may be each separately forgedof the steel most adaptedforuse in these parts and they are? separately heat treated afterwelding' according' 'to'ithe steels used and the workfthey have to erfom;

Althoughthe 'handlefhas been shown as bein'g'of I-shape in crosssection, it, maybe varied in shape-and may be'elliptic'al or oval;Having thus describedthe invention, what weclaimis: r

1. A hand tool and a forged handle'with an I shape'dshank, theheadend ofsaid shank being filled in be: tween the fiangeson both sides so thatthis comprisinga striking head,

end portion for a distance from its free end a is of substantiallyoblong transverse section so as to provide a body, of metalat said endof greater'cros s section than thatJof the I- shaped section, said headbeing a forged head with an integral. lug projecting from one sidethereof of'an'oblong crosssection substantially .the same as the headend of the shank and arranged withits greatest'width in the plane of thehead,and said free end of the shank being welded to the free end of thelug with the web of the shankextending the plane of the head. a g

2. A hatchet comprising a forged handle including a grip'portion; and anintegral shank of substantially I-shape in cross section, the head endof said shank being filled in between the flanges on both sides so thatthis end portion for a distance from its free end is of substantiallyoblong transverse section to provide a body ofmetal at said end ofgreater cross section than that of the I- shaped section, said headbeing a forged head having an integrallug of an oblong cross sectionsubstantially the same as that'of the head end of the shank projectinglaterally from one side edge of the head and arranged with its greatestwidth in the plane of the head, and said free end of the shank beingwelded to the free end of the lug with the web of the shank extending inthe plane of the head.

3. A hatchet comprising a forged handle of steel characterized bystrength and toughness including a grip portion and an integral shankofsubstantially I-shape in cross section, the head end of said shank beingfilled in between the flanges on both sides so that this end portion fora distance from its free end is of substantially oblong transr versesection to provide a body of metal at said end of greater cross: sectionthan that of the I-shaped section, said head being a forged head of acharacter of steel to receive and maintain a keen cutting edge andhavingan integral lug of an oblong cross section substantially the sameas that of the head end of the shank projecting laterally from one sideedge of the head and arranged with its greatest width in the plane ofthe head, and

said free end of the shank being welded to the free end of the lug withthe web of the shank extending in the plane of the head.

In testimony whereof we aflix our signatures.
